john is a big fan of mathematics (math) and his main interest is teaching peoplemathematics. He holds a one-day math course from time to time and is convinced that hisstudents are better at math after the course. To investigate this hypothesis, he had thefollowing experiment performed:6 students were randomly selected and theirmathematical knowledge measured before the course began (math knowledge of the).students measured before the course). The students then took the course and after that thestudents' math knowledge was measured again after the course. It can be assumed thatmathematical skills follow a normal distribution.1.What type of hypothesis test should John use to test the hypothesis that the course issuccessful?a. Hypothesis variance of two populations.b. Contingent tables for contingent tables.c. Hypothesis tests for the means of two independent populations.d. Hypothesis tests for paired measurements.e. Population variance hypothesis test.Question 2 also deals with John's course.2. Which of the following is correct about the test statistic that john should use?a. If the null hypothesis is true, the test size follows a chi-square distribution with 4degrees of freedom.b. If the null hypothesis is true, the test size follows a t-distribution with 6 degrees offreedom.c. If the null hypothesis is true, the test size follows the standard normal distribution.d. If the null hypothesis is true, the test size follows a t-distribution with 5 degrees offreedom.e. If the null hypothesis is true, the test size follows a t-distribution with 11 degrees offreedom.
